That said, I guess there are more complicated / difficult pieces of
hardware that might not do that. Is that the case here? Can we detect
that the firmware needs reloading and have the primary driver "yield" to
the firmware driver?

That doesn't really make any sense in the way USB works.

However if you've got a system to load and pin firmware on suspend and
flush it post resume then you don't actually need special 'firmware'
drivers just a slightly fancier lib/firmware that refcounts and handles
load on suspend/delayed flush.

How so? You still need to get the firmware to the device before
you unfreeze user space to get a benefit from this. Having it in
RAM is only half the deal.
